Provides a save structure from which to save Y, TREATMENTSTRUCTURE, BLOCKSTRUCTURE, COVARIATE and WEIGHTS; default * uses the current settings

Description

ASTATUS allows information to be printed and saved about the model settings and other information involved in an ANOVA analysis.

By default ASTATUS prints the current settings defined by the directives TREATMENTSTRUCTURE, BLOCKSTRUCTURE and COVARIATE. This is governed by the default setting, model, of the PRINT option. The y setting prints the name of the y-variate from the most recent ANOVA, and the weights setting prints the identifier of the variate of weights (if any). Alternatively, if the INSAVE parameter is set to the save structure from an ANOVA analysis, the y-variate, weights and model settings will be those used to form the save structure.

If the INSAVE parameter is not set, the Y parameter can be used to save the identifier of the y-variate most recently analysed by ANOVA, in a pointer of length one. The TREATMENTSTRUCTURE parameter saves the current setting defined by the TREATMENTSTRUCTURE directive (in a formula structure), and the BLOCKSTRUCTURE parameter similarly saves the current setting defined by the BLOCKSTRUCTURE directive. The COVARIATE parameter saves the current setting defined by the COVARIATE directive (in a pointer). Finally, the WEIGHTS parameter can save the identifier of the variate of weights in the most recent ANOVA, in a pointer of length one; the pointer is not formed if this was an unweighted analysis.

Alternatively, if INSAVE is set to an ANOVA save structure, the parameters Y, TREATMENTSTRUCTURE, BLOCKSTRUCTURE, COVARIATE and WEIGHTS save the settings used to form INSAVE.

The SAVE parameter saves the save structure from the most recent ANOVA (regardless of the setting of INSAVE).

Method

ASTATUS uses the GET directive to obtain the current settings of BLOCKSTRUCTURE, TREATMENTSTUCTURE and COVARIATE, and the save structure from the most recent ANOVA. It uses AKEEP, and specialist knowledge of the save structure, to obtain information from an ANOVA save structure.
